40 GIG a SECOND is INSANE

I stand corrected 1.6 tbits is insane

[AdvaitaVedantaHUB]

is it just me or are these videos amazing? thanks a lot for uploading

5:35 When he says "Half-duplex goes 400meters while full-duplex goes 2kilometers" is half-duplex just mean single mode fiber and full duplex is Multimode fiber?

from my understanding, Half-Duplex allows communication in both directions but not simultaneously. & Full-Duplex mode enables bidirectional communication.

How important would you say memorizing ethernet standards would be toward the exam?

Thank you Professor!! You’ve been helping me along my Comptia journey by explaining these topics in basic English! The way Comptia words things in their lessons is like reading a law book without knowing the dictation. Deciphering the text and trying to learn these concepts simultaneously makes it challenging to learn by myself. Maybe I’m just an illiterate fool lol formal English is definitely not my forte!

How is multi-mode fiber associated with laser? I'm confused. Shouldn't it be single mode for laser and multi mode for light?

[hannesblumel]

What is the reason that for CAT8 the increase of bandwidth is just times 4 and not 10? Does that have any correlation with usb-c thunderbold 3 also having 40gb/s?

[hmmmmmok]

How come with fiber, half-duplex has a shorter length span than full-duplex? I would've thought it would be the other way around.

I'm thinking about that 1.6Tb/s connection. Like, GTA5 would install in a matter of seconds on Steam

[walt_the_dolt]

at 2:17 it says 100BASE-TX uses 2 pair cable. Yet it also says Cat 5 is the minimum cable requirement. Cat 5 uses the normal 4 pair contact. So if cat 5 is the minimum then wouldn't it be 4 pairs of cable?

Also, another note, I think you should just put Cat 5e on the 1000BASE-T slide because Cat5 does not officially support 1gbps speeds on modern devices so it is a little confusing.

Thank you for your videos!

If I understand correctly, will ISP use a WDM Multiplexer and WDM Demultiplexer on a VPLS circuit? Since multiple companies get hosted on the same Fiber Link? Just trying to see if I understand the concept and see how it would be implemented in a real-world scenario. Thanks!

I'm kind of confused about single mode and multimode, duplex, and BiDi. So single mode and multimode can both be either full, half, or simple duplex? And is BiDi just another way to say half duplex, or is BiDi full duplex over 1 strand? or is that something different? And is the WDM thing a standard or so for half duplex?

[TalsoJesus]

What type of cables does big companies use to provide internet to home, office, etc?

Thankyou professor you helped thankyou. God bless thankyou.
